18 Claims. 1

This invention relates to a hoisting mechanism for removing a container from a basement.

One object of the invention is to provide a simple easily operated mechanism for hoisting a loaded container to an elevated point for removal, such as the window of a basement room.

A further object of the invention is to provide an apparatus by which a basket of wet clothes may be easily elevated to and moved into a window of a basement, thus avoiding the necessity of the laundress carrying the heavy load upthe basement stairs.

A further object of the invention is to' provide such a mechanism which can be manually operated with relatively little effort.

A further object of the invention is to provide such an apparatus in which the load supporting device isso counterbalanced that it can be easily moved in either direction.

A further object of the invention is to provide such a device of a compact construction which can be installed in a relatively small space.

A further-object of the invention is to provide such an apparatus of a simple constructionwhich can be manufactured and installed at low cost.

Other objects of the invention may appear as the mechanism is described in detail. I i

and Fig. 9 is a transverse section taken on the line il -9 of Fig. 8. In these drawings I have illustrated one embodiment of my invention, together with a minor modification thereof, and have shown the same as designedprimarily for installation in a domestic laundry, but it is to be understood that the mechanism as a whole, as well as the several parts thereof, may take variousforms and may be used for various purposes, without departing from the spirit 1 of the invention.

In the particular embodiment here illustrated, themechanism comprises an upright structure,

or main frame, including two upright members or bars II] which are preferably rigidly connected onewith the other by upper and lower-cross bars: 54p

l l and I2. The upright structure may be mounted in a substantially vertical position in any suitable manner but usually it is spaced a short distance from a wall 63 having therein a window M and the upright members are supported on the floor and are secured at their upper ends to the joists of the ceiling of the room. In the arrangement here shown each upright member has at its lower end a bracket It in which is mounted a threaded stud H, the stud being held rigidly in adjusted position by nuts IS. The lower end of the stud H is rounded andrests in a substantially semicircular recess l 9 in the top surface of a base or foot piece 26. The lower edge of the base rests uponthe floor and-a central stud 2! extends downwardly from the top wall of the base into a recess 22 in the floor. Thus the base is held against lateral displacement but is free to adjust itself to inequalities in the floor surface. Each upright member is provided near its upper end with alined apertured lugs 23 through which a rod z i extends, each rod being connected at its upper end with the joists of the ceiling, as by brackets '25. l The brackets may be secured directly to one of the joists or to bars extending between two joists. This method of connection permits a structure of a standard height to be installed in rooms having ceilings of difierent heights.

A carriage is supported on the upright structure for vertical movement thereon and for fore and aft tilting movement with relation thereto. The carriage and the upright members are provided with cooperating parts to guide the lower portion of the carriage in a vertical path while permitting the carriage to tilt about a transverse axis adjacent the lower end thereof. Preferably the upright members l il are in the natureofcham nel bars the flanges of which constitute guideways. are opposed one to the other and one flange of each channel" is bent inwardly as shown at 26. The carriage may take various forms and is here shown asa substantialiy rectangular frame 2?? of a length greater than the distance between the upright structure and the wall. The lower end portion of the carriage extends between the upright bars and isprovided at its opposite sides with guidemembers extending into the respective channels. In the arrangement shown alined studs 28- mount'ed on respective side members of the carriage extend laterally therefrom into there-'* spective channels, where each stud supports a roller 29 of a diameter slightly less than the width of the channel. The carriage is movably supported bycables 3D and 3|, each of which is connected In the present arrangement the channels at one end with the corresponding pivot pin 28. The cables extend upwardly along the bars H] and about sheaves 32 and 33, then downwardly about other sheaves 34 and 35 and are connected at their other ends with counterbalancing means such as a weight 36. The sheaves may be supported in any suitable manner but are preferably mounted on a bar 36a which forms a part of the upright structure.

Supported on the upper portion of the carriage is a load supporting device 3? which is here shown as a container but which may be merely a support for a container. As the carriage moves upwardly the upper portions thereof and the load supporting device are deflected rearwardly by the pivotal movement of the carriage about the common axis of the pivot pins 28. Means are provided for limiting the tilting movement of the carriage and for guiding the upper end thereof in a predetermined path. In the present arrangement inclined tracks 38 are secured to the upright bars It and extend upwardly and rearwardly therefrom to the wall 43. As here shown the upper ends of the tracks are spaced some distance from the lower edge of the window H but the tracks may terminate in any desired relation to that opening. The upper end of the carriage is provided with means for movably supporting the same on the tracks, this means preferably comprising rollers 39 which are mounted on the upper end portions of the respective side members 21a of the carriage by pins 40. The arrangement of the load supporting device is such that the weight of the load tends to tilt the carriage towards the tracks 38 and the tracks are so arranged that the carriage will be slightly so tilted when it is in its lowermost position, and the upper portion of the carriage will be slightly to the rear of the vertical plane of the transverse axis about which the carriage moves.

The load supporting device may be mounted on the carriage in any suitable manner but preferably it is mounted on arms 4! which in turn are pivotally mounted on and extend forwardly from the respective pins 49 which carry the rollers 39. The rear portion of each arm 41 is arranged between the roller 39 and the side member of the carriage 2! and the forward portion Ma of the arm is laterally offset from the rear portion thereof toward the load supporting device, thus providing between the two parts a shoulder 42 which engages the side member of the carriage and normally supports the arm in a fixed angular position with relation to the carriage, which in the present instance, is a right angle position. When, as in the present instance, the load supporting device is itself a container or basket, it is desirable that it should be removably mounted on the arms of the carriage and in the arrangement shown studs or pintles 43 are secured to and project laterally from the upper portion of the load supporting device, approximately midway between the front and rear ends thereof, and are supported in open slots 44 in the forward ends of the respective arms. The rear ends of the slots are substantially circular to form bearings for the pintle and thus permit the load supporting device to remain in a horizontal position as the positions of the arms change.

Suitable means are provided for retaining the carriage normally in its lowermost position and as here shown the retaining means comprises a spring pressed pin 45 carried by the lower transverse member 45 of the carriage I2 and a keeper 4'! on the transverse member l2 of the upright structure. When the load is to be hoisted the latch pin 45 is withdrawn from the keeper and if the load on the carriage is such that the counterweight will overbalance the same the carriage will be moved upwardly by the weight. If the load overbalances the counterweight a slight upward pressure on the load supporting device or the carriage will be sufficient to impart upward movement to the carriage and its load. The lower portion of the carriage moves vertically on the upright members 10 but the weight of the load holds the rollers 39 in contact with the tracks 38 and the upper end of the carriage and the load supporting device follow those tracks until the rollers engage the wall [3. The rollers then move upwardly on the vertical surface of the wall and the load supporting device moves in a vertical path until the rollers reach the window opening and enter the same. The rollers will enter the window opening shortly before the carriage moves to a horizontal position and the movement of the carriage to that horizontal position will cause the rollers to move outwardly over the windowsill and move the load supporting device into the window. It is desirable that the load supporting device should be moved to a position in which it projects beyond the outer side of the window so that either the load supporting device itself or the container thereon may be easily removed from the exterior of the building. To accomplish this further movement the upper portions of the shoulders 42 on the arms 4| are inclined slightly so that when the carriage moves to a horizontal position and the arms move to upright positions the weight of the load thereon will move the arms rearwardly about their axes until the inclined surfaces of the arms contact the side members of the carriage, thus moving the arms, and therefore the load outwardly with relation to the window to the position shown at Hb, in Fig. 2. A light spring 5! is connected with the arm Ma and with the carriage to return the arm to its normal position when the carriage is moved. toward its initial position. The carriage may be: returned to its initial position as soon as the load. has been removed therefrom but it may remain. in its elevated position until the basket has been; filled with dry clothes and replaced on the car-- riage. Usually the counterweights will be such as to retain the carriage in its elevated position until a downward pull is exerted thereon. A very light pull will be sufficient to restore the carriage to its initial position.

In Figs. 8 and 9 there is shown a modified form of a load supporting device, in which the device comprises a platform 48 having at its ends upwardly extending parts 49 provided with pintles 40 to enter the slots in the supporting arms 4|. Thus any suitable container may be placed on and removed from the platform.

While I have shown and described one embodiment of my invention, together with a minor modification thereof, I wish it to be understood that I do not desire to be limited to the details thereof as various modifications may occur to a person skilled in the art.
